Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: slab-out-of-bounds read in brcmf_get_assoc_ies()
Fix a slab-out-of-bounds read that occurs in kmemdup() called from
brcmf_get_assoc_ies().
The bug could occur when assoc_info->req_len, data from a URB provided
by a USB device, is bigger than the size of buffer which is defined as
WL_EXTRA_BUF_MAX.
Add the size check for req_len/resp_len of assoc_info.
Found by a modified version of syzkaller.
